FIELD OF THE INVENTION

This invention relates to a method for enhancing the expression of apolipoprotein AI, and novel compounds therefor.

BACKGROUND ART

Cholesterol is well known as a main etiologic factor for arteriosclerosis that causes severe heart diseases. Especially, increased levels of serum low density lipoprotein (LDL) are believed to be a definite risk factor for coronary heart diseases (CHDs). Remedies for decreasing the level of LDL-cholesterol (LDL-C) in plasma by use of statins have been shown to be clinically effective in preventing the onset of CHDs and improving the conditions of CHDs and survivals in patients suffering from hypercholesterolemia. However, about 40% of CHDs patients have a normal level of LDL-C, and are not always cured effectively by remedies for decreasing the level of LDL-C. On the other hand, it has been known that a half of CHDs patients having a normal level of LDL-C shows a lower level of high density lipoprotein (HDL) cholesterol (HDL-C).

Recently, the lower level of serum HDL-C has been shown to be an additional risk factor of the onset and the recurrence of CHD.

HDL plays an important role in reverse cholesterol transport system that is known as a biological mechanism to transfer an excess cholesterol in cells back to liver so as to maintain the level of cholesterol in living bodies normally.

Lipoproteins such as HDL is mainly comprised of lipids and proteins called apoprotein, and HDL comprises an apoprotein as referred to apolipoprotein AI (hereinafter, made up by apoAI) as a main component.

Excess free cholesterols (FCs) and phospholipids in peripheral cells are extracted by free apoAI to form lipoproteins called preβ-HDL(s). The excess FCs integrated in the preβ-HDLs are transformed into cholesteryl esters (CEs) by lecithin:cholesterol acyl transferase (LCAT), while the preβ-HDLs increase in their particle size to mature into spherical HDLs (HDL3s). The matured HDLs are classified into diverse subfractions based on the density, and these particles further grow up to form HDL2(s). CEs are continuously transferred into very low density lipoprotein (VLDL) and LDL by means of cholesterol ester-transporter protein (CETP). Those lipoproteins that integrate CEs are finally taken into the liver via receptors. During the course, apoAI is regenerated, and again interacts with peripheral cells to repeat the extraction of cholesterols and the regeneration of preβ-HDLs.

It has been well understood that HDL plays a central role in reverse cholesterol transport system and is a defensive factor of arteriosclerosis. It is expected that agents that promote the HDL functions could be clinically effective as medicaments for treating arteriosclerotic diseases. Accordingly, studies to develop agents that enhance the level of HDL in plasma have been conducted via various approaches.

Among them, one of the most promising approaches is to enhance the serum level of apoAI, a main component of HDL. It is understood that apoAI production increased by enhancing the expression of apoAI gene leads to directly the elevation of HDL-C level in plasma, resulting in the activation of reverse cholesterol transport system. In fact, it has been demonstrated that the mRNA level of apoAI in liver correlates closely with the levels of apoAI and HDL-C in blood (Dueland S., France D., Wang S L., Trawick J D., and Davis R A., J. Lipid Res., 38:1445-53 (1997), “Cholesterol 7alpha-hydroxylase influences the expression of hepatic apoA-I in two inbred mouse strains displaying different susceptibilities to atherosclerosis and in hepatoma cells.”). In addition, it has been shown that apoAI-transgenic mice and rabbit pathologic models administered with apoAI exhibit anti-arteriosclerosis activities (Rubin E. M., Krauss R. M., Spangler E. A., Verstuyft J. G., and Clift S. M., Nature 353, 265-267 (1991), “Inhibition of early atherogenesis in transgenic mice by human apolipoprotein AI.”; Plump A. S., Scott C. J., Breslow J. L., Proc. Natl. Acad. Sci. USA., 91, 9607-9611 (1994), “Human apolipoprotein A-I gene expression increases high density lipoprotein and suppress atherosclerosis in the apolipoprotein E-deficient mouse.”; Miyazaki A., Sakuma S., Morikawa W., Takiue T., Miake F., Terano T., Sakai M., Hakamata H., Sakamoto Y., et al., Arterioscler. Thromb. Vasc. Biol., 15, 1882-1888 (1995), “Intravenous injection of rabbit apolipoprotein A-I inhibits the progression of atherosclerosis in cholesterol-fed rabbits.”).

All those facts clearly suggest that agents that enhance the expression of apoAI would be candidates for medicaments of dyslipidemia, arteriosclerotic diseases, and other diverse diseases associated with HDL.

Compounds similar to the compounds according to the invention in terms of chemical structure are described in GB2327675, WO99/07669, WO99/24404, U.S. Pat. No. 5,670,066, DE19734438, Japanese Patent Publication (kokai) No. 41118/1994, Japanese Patent Publication (kokai) No. 14568/1991, Japanese Patent Publication (kokai) No. 253974/1992, Japanese Patent Publication (kokai) No. 147874/1999, and Journal of Pharmaceutical Sciences vol. 68, No. 7, 827-832, but the activities of these compounds are quite different from the activities according to the present invention.

Several compounds that have a chemical structure similar to the compounds of the invention, and that are described to be effective in treatment of hyperlipidemia, arteriosclerosis, and visceral fat syndrome have been known. Japanese Patent Publication (kokai) No. 68592/1991 describes the compounds that lower the level of triglycerides in plasma and consequently enhance the level of HDL-C, but the effect is caused by activating lipoprotein lipases (Goto, K., Nakamura, S., Morioka, Y., Kondo, M., Naito, S., Tsutsumi, K., Chem. Pharm. Bull., 44, 547-551 (1996), “Synthesis and Biological Activity of the Metabolites of Diethyl 4-[(4-Bromo-2-cyanophenyl)carbamoyl]-benzylphosphonate (NO-1886)”). WO98/39280 and WO98/02412 describe the compounds that inhibit acyl-CoA cholesterol acyltransferase (ACAT) thereby suppressing the accumulation of cholesterol in macrophage. Japanese Patent Publication (kokai) No. 171848/1999 describes the compounds that inhibit acetyl-CoA carboxylase thereby suppressing the biosynthesis of triglycerides. WO99/07382 describes the compounds that have an antagonist activity of macrophage scavenger receptors. Japanese Patent Publication (kokai) No. 158133/1999 describes the compounds that have activities for suppressing LDL oxidation and inhibiting ACAT. As described above, the known compounds are quite different from the compounds of the invention in terms of action mechanism.

Compounds that increase apoAI are described in Japanese Patent Publication (kokai) No. 221959/1993, Japanese Patent Publication (kokai) No. 291094/1996, and WO97/09048, but those compounds are different from the compounds of the invention in chemical structure.

EXPERIMENT 1 Activity to Enhance the Expression of Human apoAI

The promoter region of the gene encoding human apoAI was isolated, and ligated upstream the structure gene of firefly luciferase to construct a reporter plasmid. The reporter plasmid and a marker plasmid conferring the neomycin resistance were co-infected to cell lines derived from human hepatoma, HepG2 cells, and the cell lines were incubated in a selection medium comprising DMEM medium containing 10% fetal calf serum supplemented with G418 (Final concentration: 0.7 mg/mL, Gibco) to give established strains that stably expressed the reporter molecule. The strains were seeded to a 96-well culture plates at a density of 50,000 cells per well, and incubated for 48 hours at 37° C. under an atmosphere of 5% carbon dioxide. Then, a solution of the compounds according to the invention in DMSO was added to the wells at final concentrations of 0 to 10 μg/mL. After further incubation for 24 hours, the cells were added with a luciferase assay reagent (Piccagene LT 7.5 registered trade mark, Toyo Ink, KK), and the luciferase activity was determined using a luminometer (MicroBeta™ TRILUX, 1 sec/well, Wallac). The concentration of the compounds, which intensified the luciferase activity twice compared to that of control (DMSO without any compound of the invention added) was set as the minimal effective dose (MED). The results are shown in Table 25.
